Well Ermz, I can tell you that they frequently have over 100 tracks on tunes. Pick off "Today was your last day" which is the country ish song on the new album (and its an absolute killer). When i first heard it, i didnt pick a lot of stuff up as I dont listen on cans... but what originally sounded like chad and an acoustic really wasnt. There is actually a layer of bongo drums through that whole song buried deep, as well as a muted electric. I found it on cheap monitors, so i expect it should be a breeze to hear on a good setup. Very little info seems to have been published about the recording of dark horse thus far.
I have information from other albums though. I know that that ryan used a triple recto, matched cab and a triple xxx and matched cab with a single mic on each cab. Chad seems to be using Fender twins and AC30's but i dont know anything more than that about his rig. Chad and Ryan tracked once each side but two amps on each take (4 different amps totalled), and for certain areas they double it. Note, all guitar mics are SM57's. Ive heard they use marshall cabs too sometimes, and that MD 409's get used live also.
Chad has his own studio, and somehow managed to knab the greenhouses' ssl console which recorded the blackalbum and slippery when wet lol.

Vox:
NTK into Neve 1084 pre, 1176 comp, Avalon 737 SP mic processor. (apparently his favourite mic is a SM58 by MILES though for its crisp sound)
Some areas of chorus (and of course verb) on the vox. Single mono tracked, double on the choruses just like the geets. 100ms delay on most stuff, and then your proper delays on main bits.
Misc:
Acoustics: Coles Ribbon & M147
